摘　　要：We report SiO_(2)-supported monometallic Pt,Pd,Au,Ni,Cu and Co catalysts for proton-driven NAD+regeneration,co-producing H_(2).All metals are fully selective to NAD+where the order of turnover frequencies(Pt>Pd>Cu>Au,Ni and Co)coincides with those otherwise observed in electrochemical hydrogen evolution reactions.This has revealed that NADH is capable of converting the metal sites into a“cathode”without an external potential and the NADH to NAD+reaction involves transferring electron and hydrogen atom separately.Electron-deficient Ptδ+(on CeO_(2))enhances TOF and the heterogeneous Pt/CeO_(2) catalyst is recyclable without losing any activity/selectivity.
